Vibration

you mean amp stands?

I used to do it with my Wadia CD player. I imagine you are trying to get your components in between your speakers but you want them low so they don't interfere with imaging. If long as you use a good amp stand you should be OK. It really should be no different than putting the component on the lowest shelf on a rack.

Hi what are you trying to accomplish here? Lot's of great racks, amp stands, various footers...all of these things make a impact...some better some worse...

Check through the system pages here on Audiogon, you'll find plenty of systems configured with equipment on individual platforms. You can ask specific questions on those pages. You'll probably get some good, detailed answers from members who are doing it.
